Archive office documents as one PDF/A

You have a few Word documents that belong together. You want one small PDF/A to archive, in a single request.

Request

curl \
  --request POST http://localhost:3000/forms/libreoffice/convert \
  --form files=@report.docx \
  --form files=@annex.docx \
  --form 'stages=[
    { "op": "merge" },
    { "op": "remediate", "profile": "PDF/A-2b" },
    { "op": "optimize" }
  ]' \
  -o archive.pdf

Response

HTTP/1.1 200 OK
Content-Type: application/pdf

Result

One PDF/A-2b of four pages: the annex, then the report.

How it works

• LibreOffice converts each document, then the stages run on the PDFs in order: see Convert office documents.
• merge joins them in the alphanumeric order of their names. Name them 1-report.docx and 2-annex.docx to pick another order.
• remediate makes the merged PDF conform to PDF/A-2b.
• optimize comes after: it shrinks the file and keeps it conformant.

Variations

• One PDF/A per document: drop merge, and the answer is a ZIP.
• Keep the sources with the archive: make it PDF/A-3b, then attach the .docx files in a second request, with relationship: "Source" to keep the conformance. In the same request they wouldn't be converted, and attach can't follow remediate.
• Mixed formats: LibreOffice takes spreadsheets, presentations and over a hundred other formats in the same request.
